				show.c

Purpose:
	Execute show command: show the selected atoms, i.e. set hiddenF to
	zero for selected atoms.  Only the caught  complexes  are treated.
	For atoms which are not selected visibility status is not changed.

Input:
	(1) Pointer to MolComplexS structure, with macromol. complexes.
	(2) The number of macromolecular complexes.
	(3) Pointer to RuntimeS structure, with some runtime data.
	(4) Pointer to ConfigS structure, with configuration data.
	(5) Pointer to GUIS structure, with GUI data.
	(6) Pointer to NearestAtomS structure.
	(7) The number of pixels in the main window free area.
	(8) Pointer to refreshI.

Output:
	(1) The hiddenF set for each atom in each caught complex.
	(2) Return value.

Return value:
	(1) The command code.
